Comment by TKoL on Will I have any impact if I pursue a career in physics?

or am I just going to publish a bunch of irrevelant papers that nobody ever uses? -- I would actually question if perhaps this has more value than you're admitting. There are a LOT of experiment necessary to make scientific progress, and MANY of those experiments will not produce interesting results - they just confirm things we already know, or fail to confirm novel ideas. But confirming things we know, or failing to confirm novel ideas, ARE valuable scientific contributions that shouldn't be brushed aside as worthless.
